[CP2K:2055] Re: compilation HFX - sopt

[Jörg Saßmannshausen]

Dear Marc,

are you sure you got the libstdc++ actually installed?
As:
  ld: cannot find -lstdc++
looks like it the linker cannot find it and usually this would be in the 
linker search path.

You don't need these ones:
/usr/lib/gcc/x86_64-linux-gnu/4.1.2/32/libstdc++.a
/usr/lib/libstdc++.so.6
(are these files actually there??)

all you need to add is:
-lstdc++

Which distro are you using?
On rpm based distros you can do:
rpm -qa | grep libstdc*

on dpk distros you can try:
dpkg -l libstdc*

Just some sentiments.

All the best from a rainy Glasgow!

Jörg
